The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - net/sched: act_skbmod: Skip non-Ethernet packets Currently tcf_skbmod_act() assumes that packets use     Ethernet as their L2 protocol, which is not always the case. As an example, for CAN devices: $ ip link add     dev vcan0 type vcan $ ip link set up vcan0 $ tc qdisc add dev vcan0 root handle 1: htb $ tc filter add dev     vcan0 parent 1: protocol ip prio 10 \ matchall action skbmod swap mac Doing the above silently corrupts     all the packets. Do not perform skbmod actions for non-Ethernet packets. (CVE-2021-47293)

Note that Nessus relies on the presence of the package as reported by the vendor.
